Description

Technical Field

[0001] This utility model relates to the field of fly ash treatment technology, and in particular to a device for sedimentation and separation of fly ash washing liquid. Background Technology

[0002] Municipal solid waste incineration technology has been rapidly promoted and applied in recent years; however, the amount of fly ash generated after incineration is also increasing daily.

The geared motor 201a is started, and its output rotates clockwise, driving rotating rod 201b to rotate clockwise. Rotating rod 201b, through connecting sleeve 201c and connecting rod 201d, drives stirring plate 201e to rotate. The coagulant and flocculant are evenly mixed in the fly ash washing liquid. After a period of stillness, the fly ash washing liquid settles, and the sediment falls into sedimentation tank 102. The lower connecting cover 107 is then removed, and the output of geared motor 201a rotates counterclockwise. When the needle rotates, the rotating rod 201b and the cylindrical rod 202a rotate counterclockwise. The cylindrical rod 202a drives the scraper 202c to rotate via the crossbar 202b. The scraper 202c scrapes away the sediment adhering to the inner wall of the sedimentation tank 102. When the cylindrical rod 202a rotates counterclockwise, it drives the screw 203a to move downward. The screw 203a drives the rectangular block 203b to move down into the rectangular groove of the vertical rod 204, thereby driving the vertical rod 204 to rotate. The vertical rod 204 drives the stirring plate 206 to rotate via the connecting shaft 205. The stirring plate 206 stirs the sediment in the sedimentation tank 102, loosening the sediment. The loosened sediment is discharged through the spiral conveyor plate 208.
